I was going to say there are absolutely no situations where this is  
not true, however in your case autocommit or not it doesn't matter.
You have a single connection for the entire application and  
asynchronous events using that connection. Autocommit or not it will  
not work with currval.

In your case you must use nextval before doing the insert.
